#10: Welcome to the Bat Cave
While this sign may not have been intended to be humorous, it certainly ended up that way. Nobody wants to be a bat’s toilet! You’ve got to give this sign props–it definitely gets your attention. It’s probably saved a lot of people from getting pooped on, which is something they can take pride in.
In reality, how many people would want to visit a free-flying bat enclosure, especially if they knew there was a big chance of bat poop raining down on them? Bats can be creepy creatures, but the added risk of their waste landing on your face makes things even worse.
